It is definitely lack of experience. I do have self-doubt but I don't think it is so imposing that I am ignoring signs. I suppose just the general vibe I get from him is much different than the other guys that have approached me with a clear intent of liking me. When he says stuff like how he doesn't care about me, I assume that he's joking, but really I can't tell if he's serious or not. To be honest, I always thought that him brushing hair out of my face was just a mild ocd trait of his and nothing more. Additionally, I thought his stares were just either out of boredom or him just being a pervert.
